(fine->coarse) Populates all the active voxel values in the coarse (level) tree from the fine (level-1) tree using trilinear interpolation. For cell-centered data, this is equivalent to an average For vertex-centered data this is equivalent to transferring the data from the fine vertex directly above the coarse vertex. This transforms multiple values of the tree in parallel
